Objective: This study investigated the effects of the administration of ethanolic saffron petal extract (SPE) and vitamin E (Vit E) on growth performance, blood metabolites and anti-oxidant status in Baluchi lambs. Methods: Thirty-two Baluchi male lambs ($35.22{\pm}5.75kg$) were randomly divided into 4 groups. The 1st (control), 2nd (injectable saffron petal extract [ISPE]), and 3rd (Vit E) groups were respectively injected subcutaneously with either physiological saline (5 mL), SPE (25 mg/kg body weight [BW]) or DL-${\alpha}$-tocopheryl acetate (225 IU) once a week. An oral dose of SPE (500 mg/kg BW) was also administered to the 4th group (oral saffron petal extract [OSPE]). Feed intake and BW were measured for 42 days and blood samples were taken on days 1, 14, 28, and 42. The lambs were slaughtered, and tissue samples were taken. Results: Growth performance and many blood metabolites were not affected (p>0.05) by the treatments. Cholesterol of plasma in the ISPE and Vit E groups was similar and less (p<0.01) than both the OSPE and control groups. Although there was no significant difference between the control and other groups for plasma triglyceride, the ISPE group showed lower (p<0.05) triglyceride than the OSPE and Vit E groups. The highest (p<0.01) plasma glutathione peroxidase (GPx) was detected in the OSPE group, while the ISPE and Vit E groups showed higher (p<0.01) superoxide dismutase (SOD) of plasma than the control. Malondialdehyde of plasma in the ISPE group was lower (p<0.05) than the OSPE. No differences (p>0.05) were observed among the groups for antioxidant status of both longissimus dorsi muscle and liver. However, the activity of GPx in the kidney and heart, as well as SOD activity in the kidney, were influenced ($p{\leq}0.01$) by the treatments. Conclusion: Adding ethanolic SPE improved antioxidant status and lowered lipids oxidation in lambs. The SPE and Vit E demonstrated similar effects on antioxidant status in lambs.

Purpose: The purpose of this study was to differentiate between women with three perimenstrual symptom severity patterns : premenstrual syndrome(PMS), premenstrual magnification(PMM), and low symptom(LS), and to explore the related dietary factors to premenstrual symptoms. Method: Women were asked to keep a diary record of perimenstrual symptoms and food intake for 50 days. Result: Symptom patterns were defined for 26 among 38 women ; Eight(21.1%) demonstrated a PMS pattern, three(7.9%) demonstrated a PMM pattern, and fifteen(39.5%) exhibited a LS pattern. There were significant differences in symptom scores during the premenstrual phase($x^2=19.30$, p=.000), menstrual phase($x^2=13.32$, p=.001), and post menstrual phase($x^2=9.93$, p=.007) for three groups. Protein, vit E, vit C, niacin, folic acid, and phosphorus in the premenstrual phase, and energy, and vit B6 in the menstrual period were significantly different between the three groups. Among dietary compositions, amino acids, lipids, fatty acids, saturated fatty acids, natrium, vit B6, niacin, and vit E were negatively related to PMS symptoms. Conclusion: Pattern of perimenstrual symptoms should be differentiated for individualized PMS management. As a more efficient diet assessment for PMS women, randomized nutritional analysis during the 3 phases of the menstrual cycle should be done and a replication study is necessary with a larger sample.

This study was conducted to investigate the nutritional intake of people in rural areas using 24-hour recall method. Kyungki Yeoju, Kangwon Whengsung, Chungbuk Chungju, Kyungnam Ulju, and Junbuk Jungup were selected for this study. The results were as follows 1) The mean daily energy intake was 2055.7kcal for male, 1703.2kcal for female. Fat intake were 43.0g for male, 32.7g for (female and protein intake was 74.5g for male 61.5g for female. Nutrient intake of Ulju residents were the highest and that of Whengsung and Yeoju residents were the lowest. Nutrient intake decreased significantly in elderly over 70 years. 2) Nutrients consumed below 80% of Korean RDA were Ca, Vit A, riboflavin and Vit E. Ulju residents consumed significantly higher protein, Ca, P compared to other area residents. P, Fe, Vit C intake of adults male were significantly higher than those of elderly over 80 years. Vit A, thiamin and riboflavin consumption of adults female were also significantly higher than those of elderly over 80 years. Ca, Vit A, riboflavin and Vit I were consumed below the Korean RDA in both male and female. 3) Average CPF ratio of energy intake was 69.2 : 14 : 16.8. Energy intake ratio from carbohydrate was significantly lower in Ulju residents compared to Yeoju and Jungup residents. Energy intake ratio from protein was significantly higher in Ulju area than the other areas. Carbohydrate dependency was increased with age, meanwhile fat dependency was decreased with age. 4) The mean adequacy ratio(MAR), an index of overall dietary quality, were significantly different among areas : the highest was 0.81 in Ulju, the lowest was 0.65 in Whengsung. Adults of 20-49 years showed the highest MAR of 0.76 and the lowest MAR was 0.52 in over 80 years group. The indexes of nutritional quality(INQ) was higher in 01;u area than the other areas, and INQ showed the tendency to decrease with increasing age. Especially, there were significant decrease in INQ of all nutrients except Vit A with age. Based on these results, it is evident that people in rural area did not consume enough nutrients. Specially, dietary intake of Vit A, Vit B$_2$, Vit E and Ca were not adequate. (Korean J Nutrition 31(9) : 1468-1480, 1998)

Curcumin (CMN) is known to have beneficial role in anorexia, coryza, cough, diabetic wounds, and hepatic disorders apart from its inherent antioxidant effects. Therefore, the present study was aimed to evaluate antioxidant effect of CMN in prevention of nephrolithiasis in rats-induced by ethylene glycol (EG) and Vitamin D3 (Vit. D3). Male Wistar rats (175 - 200 g) were randomized in groups like control, EG + Vit. D3 induced nephrolithiatiatic rats, CMN treated rats, CMN + EG + Vit. D3 treated rats, Vit. E + EG + Vit. D3 treated rats. Urine was collected weekly throughout the experimental protocol and estimated for calcium oxalate (CaO) count. After completion of experimental protocol serum was estimated for blood urea nitrogen and creatinine. Both the kidneys were excised and used to evaluate levels of biomarkers of oxidative stress and calcium oxalate crystal deposition by histopathological studies. Administration of EG and Vit. D3 to rats resulted in increased oxidative stress, hyperoxaluria and renal deposition of CaO crystals. Supplementation with CMN improves kidney function, reduces elevated oxidative stress, urinary oxalate level and renal deposition of CaO which shows its protective action in nephrolithiasis. The increased deposition of stone in the kidney and stone forming constituents of nephrolithiatic rats were effectively lowered by treatment of CMN.

Due to the fact that tocopherols and tocotrienols have antioxidant and anticancer properties, the commercial utilization of unsaponifiable fractions in rice bran is increasing. These nutraceutical compounds, however, are fairly unstable and readily break down when exposed to oxygen or lighting conditions. To compare the relative sensitivity of vit E isomers to heat and oxygen, concentrated unsaponifiable fractions extracted from crude rice bran oil were exposed to various temperature, oxygen (nitrogen-balanced), and bathing solvent conditions and resultant concentration changes in ${\alpha}$- and ${\gamma}$-tocopherols (T) and tocotrienols (T3) were evaluated. Each isomer exhibited different heat stability. Among them, ${\alpha}$-T3 degraded more rapidly compared to other vit E isomers while ${\alpha}$-T was the most stable isomer. Oxygen level also showed significant impact on each isomer's stability where severe reductions of ${\gamma}$-T (by 20%) and ${\gamma}$-T3 (by 29%) were observed under 2% oxygen conditions, while under 0% oxygen conditions no degradation could be observed even after exposure to $95^{\circ}C$ for 4 hours. When various blending solvents were mixed with concentrated unsaponifiable fractions, organic solvents such as isooctane and hexane were more effective in maintaining the stability of ${\gamma}$- T3 compared to edible oils, among which com oil was more efficient than soybean and rice bran oils.

The reactive intermediates formed during the metabolism of therapeutic agents, toxicants and carcinogens by cytochromes P450 are frequently capable of covalently binding to tissue macromolecules and causing tissue damage. It has been shown that YH439, a congener of malotilate, is effective in suppressing hepatic P450 2E1 expression. The present study was designed to further establish the mechanistic basis of YH439 protection against toxicant by assessing its effects against chemical-mediated potentiated hepatotoxicity. Retinoyl palmitate (Vit-A) pretreatment of rats for 7 days substantially enhanced carbon tetrachloride hepatotoxicity, as supported by an ${\sim}5-fold$ increase in serum alanine aminotransferase (ALT) activity, as compared to $CCl_4$ treatment alone. The elevation of ALT activity due to Vit-A was completely blocked by the treatment of $GdCl_3$ a selective inhibitor of Kupffer cell activity. Concomitant pretreatment of rats with both YH439 and Vit-A resulted in a 94% decrease in Vit-A-potentiated $CCl_4$ hepatotoxicity. YH439 was also effective against propyl sulfide-potentiated $CCl_4-induced$ hepatotoxicity. Whereas propyl sulfide (50 mg/kg, 7d) enhanced $CCl_4-induced$ hepatotoxicity by >5-fold, relative to $CCl_4$ treatment alone, concomitant treatment of animals with both propyl sulfide and YH439 at the doses of 100 and 200 mg/kg prevented propyl sulfide-potentiated $CCl_4$ hepatotoxicity by 35% and 90%, respectively. Allyl sulfide, a suppressant of hepatic P450 2E1 expression, completely blocked the propyl sulfide-enhanced hepatotoxicity, indicating that propyl sulfide potentiation of $CCl_4$ hepatotoxicity was highly associated with the expression of P450 2E1 and that YH439 blocked the propyl sulfide-enhanced hepatotoxicity through modulation of P450 2E1 levels. Propyl sulfide- and $CCl_4-induced$ stimulation of lipid peroxidation was also suppressed by YH439 in a dose-related manner, as supported by decreases in malonedialdehyde production. The role of P450 2E1 induction in the potentiation of $CCl_4$ toxicity and the effects of YH439 were further evaluated using pyridine as a P450 2E1 inducer. Pyridine pretreatment substantially enhanced the $CCl_4$ hepatotoicity by 23-fold, relative to $CCl_4$ alone. YH439, however, failed to reduce the pyridine-potentiated toxicity, suggesting that the other form(s) of cytochroms P450 inducible by pyridine, but not suppressible by YH439 treatment, may play a role in potentiating $CCl_4-induced$ hepatotoxicity. YH439 was capable of blocking cadmium chloride-induced liver toxicity in mice. These results demonstrated that YH439 efficiently blocks Vit-A-enhanced hepatotoxiciy through Kupffer cell inactivation and that the suppression of P450 2E1 expression by YH439 is highly associated with blocking of propyl sulfide-mediated hepatotoxicity.

The aim of this study was to evaluate the in vivo effect of galangin and the 70% ethanolic extract of Alpinia officinarum (AO) toward $KBrO_3$-induced DNA and chromosomal damage in mice. Galangin and AO inhibited the formation of 8-hydroxy-2'-deoxyguanosine (8-OH2'dG) as an indicator of DNA oxidative damage in the liver cell. Galangin and AO showed the inhibitory effect on the formation of DNA single strand break in the splenocyte by single cell gel electrophoresis (SCGE) assay and also inhibited micronucleated reticulocyte (MNRET) formation of peripheral blood in tail blood of mice. Vit-E revealed antigenotoxic effects in DNA and chromosome levels, but galangin was more potent active compound compare to vit-E under our experimental conditions. The results suggest that the extract of Alpinia officinarum containing galangin can modify the oxidative DNA and chromosomal damage and may act as chemopreventive agent against oxidative stress in vivo.

The purpose of this study was to examine household food insecurity and the associations of food insecurity with socioeconomic characteristics, food behaviors, health status and nutrient intake among elderly people in a rural area. This study included 191 elderly people (mean age = $72.0{\pm}7.4$) in Jeollabuk-do, Jangsu-gun. House food insecurity was measured using an adapted version of the USDA short form household food insecurity scale, and nutrient intake measured by a 24-hour dietary recall. Only 15.2% of the subjects were in food-insecure households, 84.8% of the elderly households were food-secure. The food-insecure households were significantly lower in the number of family, frequency of shopping, and perceived health status than the food-secure households. In addition, they had serious tooth problems and NSI (Nutrition Screening Index) scores. Food-insecure households were significantly lower in most areas of nutrient intake (energy, protein, fat, Ca, P, Fe, K, Na, Zn, Vit. $B_2$, niacin, Vit. E), and also lower in nutrient intake compared to dietary reference intake (energy, protein, P, Fe, K, Na, Vit. $B_1$, Vit. $B_2$, niacin, Vit. E). These results suggest that the household food insecurity measures used in this study were an important indicator of nutritional well-being among elderly persons in the rural area. Food insecurity should be considered an important issue to public health and food service programs should be expanded for food-insecure households in rural areas.

The purpose of this study was to investigate the effect of H$_2$O fraction of Dioscorea japonica Thunb (DJT) with vitamin E on blood glucose and fat metabolism in streptozotocin (STZ) diabetic rats. Sprague-Dawley rats (200∼230 g) weighing were divided into five groups; the normal group, the STZ-control group, the DJT group, the DJT-vitamin E group and the vitamin E group. Diabetes was induced in the male rats by injection of STZ into tail vein at a dose of 45 mg/kg body weight. The H$_2$O fraction of DR (500 mg/kg) and 10 mg/kg of vitamin E (㎗-${\alpha}$-tocopherol) given orally were administered for 14 days. The body weight was monitored and levels of hematocrit, protein and glucose were determined. The plasma concentrations of cholesterol; triglyceride, free fatty acid and HDL-cholesterol were measured. The activities of aminotranseferase were analysed. The body weight gain was shown no significantly higher in the normal group than all STZ groups. The administration of H$_2$O fraction of DJT and vitamin E showed a significant increase in plasma protein concentrations. The all STZ group was formed to be effective in decreasing blood glucose levels. Plasma insulin concentrations were highered in diabetic rats fed on H$_2$O fraction of DJT. Plasma triglyceride and free fatty acid levels were lower in the vitamin E group than the STZ-control group. The plasma cholesterol levels of all STZ groups were not significantly different and HDL-cholesterol levels were increased in all STZ groups fed on H$_2$O fraction of DJT and vitamin E, specially in the DJT-vit. E group. The all STZ group does not significantly change aminotransferase activity of diabetic rats. These results indicated that DJT was a potential candidate for a treatment of diabetes which can enhance insulin activity The effect of vitamin E on insulin activity will be examined in more detail.
